How to Patch and Compile Linux Kernel for a specific issue? (No sound in HP ENVY x360 2-in-1 Laptop 15-ey0xxx)

I got the exact same problem as the person here: https://unix.stackexchange.com/q/722205/572281 and I want to patch and recompile my kernel with: https://lore.kernel.org/lkml/20220811053950.11810-1-faenkhauser@gmail.com/ I know there are a bunch of tutorials how to patch and compile the kernel, but I need this specific change that, as I understand, is not officially included in a kernel version. Correct me if I'm wrong. What do I have to do? I don't know how where start and I don't even know how to get the patch from the link. I use Arch Linux, btw. But I am a newbie. My Kernel Version: 6.3.1-arch2-1
